Forbes has quoted Informatica as the next Microsoft, this itself reflects the market share Informatica is having over its competitors.

Why do we need Informatica?

Informatica comes to the picture wherever we have a data system available and at the backend we want to perform certain operations on the data. It can be like cleaning up of data, modifying the data, etc. based on certain set of rules or simply loading of bulk data from one system to another.

Informatica offers a rich set of features like operations at row level on data, integration of data from multiple structured, semi-structured or unstructured systems, scheduling of data operation. It also has the feature of metadata, so the information about the process and data operations are also preserved.

  • It provides high visibility in case of presentations for the visual data.
  • It provides easy data maintenance and data monitoring.

Why it is used?

The conventional application for Informatica is:

  • The company uses it to transfer from the current legacy system such as mainframe to the latest system of database. Consequently, the transfer of its existent data into the system could be carried out.
  • Companies establishing their warehouses of data will need a tool of ETL to transfer the data to the warehouse from the Production system.
  • The assimilation of information from several different systems such as numerous databases and system based on files could be completed utilizing Informatica.
  • It could be utilized as a tool for cleansing data.

It is beneficial more than it provides a broad collection of product versions. Hence, consumers could choose a particular edition based on requisite. Informatica is consistently emphasized as a product of the integration of data product leader in the listing of Gartner Magic Quadrant.

When you are browsing several webpages to locate the drawbacks of Informatics you might not be able to find any as there are very few drawbacks. This section comprises information that is never more shown on any other article. Below you might a few disadvantages:

  • Workflow Monitor lack of sorting
  • In the workflow monitor, there is no choice to separate out folders that are required or needed
  • In the repository manager, it not possible to move an object from one folder to another
  • Further, you cannot import XML export files
  • Also, it includes Mappings and workflows development is also not possible.

Informatica Architecture Tutorial: The Ultimate Guide [STEP-IN]

Informatica architecture is service-oriented architecture (SOA). A service-oriented architecture is defined as a group of services that communicate with each other. It means a simple data transfer during this communication, or it can be two or more services that coordinate the same activity.

  • The Informatica development depends upon the component-based development techniques. This technique uses the predefined components and functional units with their functionalities to get the result.
  • PowerCenter is based on the component-based development methodologies. To build a dataflow from the source to target, it used different components, and this process is called transformation.
  • Basically, Informatica Power centre consists of the following components and services.
  • Repository Service: – responsible to maintain the metadata of Informatica and to provide access to other services.
  • Integration Service: – This service is responsible for the movement of the data to the target from the source.
  • Reporting Service: – Responsible for generating reports.
  • Nodes: – They are the computing platforms and the above services are executed here.
  • Informatica Designer: – Helps in creating mapping between the target and the source.
  • Workflow Manager: – This is responsible for creating workflows and related tasks. Also helps in executing them.
  • Workflow Monitor: – As the name indicates, it monitors the execution of workflow.
  • Repository Manager: – Responsible for managing objects in repository.

Informatica Domain

  • The Informatica domain is the fundamental administrative unit.
  • The Informatica domain consists of nodes and services. These nodes and services are categorized into folders or sub-folders based on administration requirements and design architecture.
  • The Console web page of the Informatica administrator creates a domain that looks like a folder. Inside this folder, we can create a node with the services.
  • In the Informatica domain, a node is a logical representation of the machine. All the services and processes run inside the domain in the Informatica. Multiple nodes can be present in a single domain. A gateway node receives the request from the clients and guides them to their respective services.
  • The domain provides two types of services, such as:
  1. 1. Service Manager: It manages domain operations such as logging, authentication, and authorization. It runs the application services on the nodes and leads users and groups.
  2. 2. Application Services: It represents the server-specific services such as repository services, reporting services, and integration services. The application service can run on different nodes based on configuration.

PowerCenter Repository

  • PowerCenter repository is a relational database like Oracle, Sybase, SQL server and it is managed by repository service. It consists of database tables that store metadata.
  • There are three Informatica Client tools available in Informatica Powercenter. They are Informatica
  • Designer
  • Workflow Monitor
  • Workflow Manager
  • These clients can access to the repository using repository service only.
  • To manage a repository there exists an Informatica service called Repository Service. A single repository service handles exclusively only one repository. Also, a repository service can execute on multiple nodes to increase the performance.
  • The repository services use locks on the objects, so multiple users cannot modify the same object same time.
  • You can enable version control in the repository. With the version control feature, you can maintain different versions of the same object.

Objects created in the repository can have following three state

  • Valid: Valid objects are those objects whose syntax is correct according to Informatica. These objects can be used in the execution of workflows.
  • Invalid: Invalid objects are those who does not adhere to the standard or rules specified. When any object is saved in Informatica, it is checked whether its syntax and properties are valid or not, and the object is marked with the status accordingly.
  • Impacted: Impacted objects are those whose child objects are invalid. For example in a mapping if you are using a reusable transformation, and this transformation object becomes invalid then the mapping will be marked as impacted.

Key properties of the domain are

  • Resilience timeout – If any of the integration service or repository services goes down then resilience timeout is the no of seconds the application service tries to connect to those services.
  • Restart Period – It is the maximum number of seconds the domain spends to restart a service.
  • Dispatch Mode – It is the policy used by the load balancer to dispatch tasks to various nodes.
  • Database type – The type of database on which domain is configured.
  • Database host – Hostname of the machine on which domain is configured.
  • Database port & name – It is the database port and the database instance name for the domain.

Powercenter client & Server Connectivity

  • PowerCenter client tools are development tools which are installed on the client machines. Powercenter designer, workflow manager, a repository manager, and workflow monitor are the main client tools.
  • The mappings and objects that we create in these client tools are saved in the Informatica repository which resides on the Informatica server. So the client tools must have network connectivity to the server.
  • On the other hand, PowerCenter client connects to the sources and targets to import the metadata and source/target structure definitions. So it also must have connectivity to the source/target systems.
  • To connect to the integration service and repository service, PowerCenter client uses TCP/IP protocols and
  • To connect to the sources/targets, the PowerCenter client uses ODBC drivers.
